Day 4 of #100DaysOfCode: Building My First Square App with Glitch

Today I built my first working Square app!

I started with Square's official Order-Ahead Sample App, a Node/Express project.

Following its accompanying tutorial in the Square docs:

Configuration

I created an Order Ahead app in https://developer.squareup.com/apps/ (you need a Square account to do this)

I updated config.json with the sandbox app ID and token.

Running npm test failed. I did npm install and tried again. It worked:

$ npm test

> order-ahead-sample-app@0.0.0 test /Users/arg/projects/3rd-party/connect-api-examples/connect-examples/v2/node_orders-payments
> NODE_ENV=sandbox node ./bin/www

First Local Run

I went to http://localhost:3000/ and saw a page with "Sandbox Location Business Nickname" at the top. Yay, the app runs locally!

Generating Test Data

I ran the example script to seed the sandbox store catalog with test data. It generated a bunch of restaurant food items:

$ npm run seed

> order-ahead-sample-app@0.0.0 seed /Users/arg/projects/3rd-party/connect-api-examples/connect-examples/v2/node_orders-payments
> NODE_ENV=sandbox node ./bin/script/seed-catalog.js generate

Successfully uploaded item: #Italian Sandwich
Successfully uploaded item: #Steak Tacos
Successfully uploaded item: #Autumn Soup
Successfully uploaded item: #Sunny-Side Egg on Toast
Successfully uploaded item: #Fried Chicken Sandwich
Successfully uploaded item: #Salmon with Zucchini
Successfully uploaded item: #Oatmeal with Fruit
Successfully uploaded item: #Mediterranean Yogurt Bowl
Successfully uploaded item: #Meatballs
Successfully uploaded item: #Pancakes with Fruit
Successfully uploaded item: #Bacon Cheeseburger
Successfully uploaded item: #Grilled Steak

Placing a Sample Order

Restarting the local server with npm test, I now see those test items. I can click them to see a pop-up with detail and a Buy This button:

Clicking Buy This leads to Choose Delivery Method:

• Under Delivery Method, the only option is Pickup.
• Under Pickup Location, the only option is Sandbox Location Business Nickname.

The next screen was Review and Complete Your Order. I entered the test card:

I clicked Pay with Card and it gave me this Order Confirmation:

Verifying the Order in the Sandbox

Sure enough, the order shows up under Orders:

I can mark it In Progress, then Ready, then Picked Up using the upper right button.

That's great that the sample Square app works locally.

Getting It Running on Glitch

I made a copy of the node_orders-payments folder as OrderAhead.

I copied GitHub's Node.gitignore as the project .gitignore.

The code's now in a GitHub repo: https://github.com/feldroy/OrderAhead

In Glitch, I clicked New Project > Clone from Git Repo and pasted in [e-mail]:feldroy/OrderAhead.git. The screen went black and it didn't like that. I tried again with https://github.com/feldroy/OrderAhead.git and that worked.

The Square tutorial had me put credentials into config.json earlier, which I .gitignored. I moved those to .env and now load them from there in util/square-connect-client.js:

const config = {
  "path": "https://connect.squareupsandbox.com",
  "squareApplicationId": process.env.SQUARE_APPLICATION_ID,
  "squareAccessToken": process.env.SQUARE_ACCESS_TOKEN
}

Here's the Glitch app:

The Deployed Demo Site

You can experiment with this and even place test orders using the demo credit card.

Finally, if you're new to Square, here's an invite to get free processing on up to $1,000 in credit card transactions for the first 180 days.

Hey! Great work.
I am a newbie and testing the sample app for a school project. However, I am hitting an error and no matter what trouble shooting I do, I cant get past step two on the sqquare up example.

For npm test I get the following error

echo 'Error: no test specified'

'Error: no test specified'

I have tried the trouble shoots such as replacing ttest in the package.json file with the following;
"scripts": {
"start": "NODE_ENV=production nodemon -e js,pug ./bin/www",
"test": "mocha",
This didnt work. I have also noticed that some files might have been changed or updated in the squareup github files but these are not being reflected in the steps (which is a possibility).

Hopefully you can point me in the right direction?
